Hello, I have a file with name: PPSFAR65_DKMAR_CUST_QUERY-3865422.xls. Everyday it needs to be renamed to PPSFAR65_DKMAR_CUST_QUERY.xls. It was working fine till I started getting couple more files: PPSFAR66_MARBS_CUST_QUERY-3865420.xls and PPSFAR67_PMNT_ON_SIS_INVC-3865419.xls. With the addition of the new files, even though I pass parameter, PPSFAR65_DKMAR_CUST_QUERY.xls, it goes and updates file PPSFAR67_PMNT_ON_SIS_INVC-3865419.xls as that is the latest file. Here is code I have: 
#!/usr/bin/perl
# Syntax : /../perl /.../PS_file_Rename.pl -s /..../Source_directory -
+f filename.xls
#    .. -> path of Perl.exe
#   ... -> path of the script PS_file_Rename.pl
# -s option - Source_Folder
# -f option - Filename to use for renaming
use Getopt::Std;
use Data::Dumper;
use POSIX qw(strftime);
use vars qw($opt_s $opt_f);
getopts('s:f:');
$ff="$opt_s"."\\"."$opt_f";
#if the file name already exists delete it
if (-e $ff)
{
       unlink($ff) or  warn scalar localtime(time()), " WARN Can't del
+ete $ff : $!";
}
my $path =  $opt_s."\\*.*";
$path =~ s|\\|/|g;
#find the newest file
my $newestfile = (sort{(stat $b)[10] <=> (stat $a)[10]}glob $path)[0];
#rename the newest file to the name passed
rename($newestfile,$ff) or  warn scalar localtime(time()), " WARN Can'
+t rename $newestfile : $!";
@files = glob $opt_s."\\*.*";
foreach my $file (@files)
{
    if($file ne $ff)
   {
       unlink($file) or  warn scalar localtime(time()), " WARN Can't d
+elete ".$opt_s."\\".$file." : $!";
  }
}
